Why do people read something on the internet and immediately have an uninformed opinion about it?

Question

Why is it that people throw URL's (half of which are wikipedia or some other non-reputable source) around and preach to others how stupid they are for not believing in some "information fad?" If I can't stand up and state "You are wrong" without a million drones saying "Wikipedia says YOU are wrong and Wikipedia is never wrong (insert derogatory comment here)" then why bother with freedom of speech; for I do not have freedom of thought.

Furthermore, for all the effort these people take to preach, they take little to no effort to actually help. (P.S. Recycling is BAD, most Waste Management services automatically separate recyclables from non-recycleables by law... only thing putting stuff in the blue box does is reduce jobs [which hurts the economy... chew on THAT :P)

Answer 1

People in our world today feel powerless, they get no respect and live in fear of being controlled by others. Got to go to work, cant - the old ball and chain ya know, That is against the law, and on and on - by stating their views they believe they retain a sense of respect to fill the voids in their life - mostly to feel like - Hey I am somebody!

Answer 2

Every one is allowed an opinion doesn't mean you have to listen the only persons opinion that matters is......You guessed it number ONE  

Answer 3

Because people are too lazy to actually think for themselves these days.  They just take whatever sounds best.  

There is sooooooo much advice about every single topic that it's impossible to know what's right, or find something even close to the truth.
